Answer:
(a) See below
(b) 103.935 °F; 102.235 °F
Explanation:
The equation relating the temperature to time is
1. Calculate the thermometer readings after 0.5 min and 1 min
(a) After 0.5 min
(b) After 1 min
2. Calculate the thermometer reading after 2.0 min
T₀ =106.321 °F
ΔT = 100 - 106.321 °F = -6.321 °F
t = t - 1, because the cooling starts 1 min late
3. Plot the temperature readings as a function of time.
The graphs are shown below.
Answer:
2,7 m
Explanation:
You can solve this doing an energy balance:
Solving this equation to get h:
Replacing the values and solving brings to 2,7 m
The complete question is as follows: Which statement describes the way in which energy moves between a system reacting substances in the surroundings.
A) molecule Collisions transfer thermal energy between the system and its surroundings
B) The thermal energy of the system and it’s surroundings increase
C) The potential energy of the system and it’s surroundings increases
D) molecular collisions create energy that is then released into the surroundings
Answer: The statement, molecule Collisions transfer thermal energy between the system and its surroundings describes the way in which energy moves between a system reacting substances in the surroundings.
Explanation:
When there will occur an increase in kinetic energy of molecules then there will occur more number of collisions.
When kinetic energy between these molecules tends to decrease then they will release heat energy into their surroundings.
As a result, it means that molecule collisions transfer thermal energy between the system and its surroundings.
Thus, we can conclude that the statement molecule Collisions transfer thermal energy between the system and its surroundings describes the way in which energy moves between a system reacting substances in the surroundings.
